A firearm is a weapon that launches one or more projectile(s) at high velocity through confined burning of a propellant. This subsonic burning process is technically known as deflagration, as opposed to supersonic combustion known as a detonation. In older firearms, the propellant was typically black powder, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore firearms) have...

A firearm is a weapon that launches one or more projectile(s) at high velocity through confined burning of a propellant. This subsonic burning process is technically known as deflagration, as opposed to supersonic combustion known as a detonation. In older firearms, the propellant was typically black powder, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore firearms) have rifled barrels to impart spin to the projectile for improved flight stability.
Beginning around 700 A.D., scientists and inventors in Ancient China developed different grades of gunpowder and different types of firearms, including single-shot smooth-bore fire lances, multi-barreled guns, multiple-launch artillery rockets and the first cannon in the world made from cast bronze. Several centuries later, in late Dark Age Europe, the term "firearm" was used in Old English to denote the arm in which the match was held that was used to light the...
